论文摘要
免疫反应是一个动态过程,通过该过程,身体决定抗原是自我还是非自然的。这种动态过程的状态由构成该决策过程的炎症和监管参与者的相对平衡和种群定义。免疫疗法的目的,例如因此,类风湿关节炎(RA)是为了使免疫状态偏向于监管参与者,从而在反应中关闭自身免疫性途径。尽管有几种已知的免疫疗法方法,但治疗的有效性将取决于这种干预措施如何改变该状态的演变。不幸的是,此过程不仅取决于过程的动力学,而且是在干预时的系统状态决定的,这种状态在应用治疗之前很难确定即使不是不可能的状态。为了识别这种状态,我们考虑了RA(胶原蛋白诱导的关节炎(CIA))免疫疗法的小鼠模型。通过最近开发的CIA免疫疗法治疗后,收集有关小鼠T细胞标记和种群的高维数据;并使用特征选择算法以选择该数据的较低维子集,该算法可用于预测全套T细胞标记和人群以及免疫疗法治疗的功效。
The immune response is a dynamic process by which the body determines whether an antigen is self or nonself. The state of this dynamic process is defined by the relative balance and population of inflammatory and regulatory actors which comprise this decision making process. The goal of immunotherapy as applied to, e.g. Rheumatoid Arthritis (RA), then, is to bias the immune state in favor of the regulatory actors - thereby shutting down autoimmune pathways in the response. While there are several known approaches to immunotherapy, the effectiveness of the therapy will depend on how this intervention alters the evolution of this state. Unfortunately, this process is determined not only by the dynamics of the process, but the state of the system at the time of intervention - a state which is difficult if not impossible to determine prior to application of the therapy. To identify such states we consider a mouse model of RA (Collagen-Induced Arthritis (CIA)) immunotherapy; collect high dimensional data on T cell markers and populations of mice after treatment with a recently developed immunotherapy for CIA; and use feature selection algorithms in order to select a lower dimensional subset of this data which can be used to predict both the full set of T cell markers and populations, along with the efficacy of immunotherapy treatment.
